College career
Kline was recruited by Mid-American Conference schools and chose to attend Kent State in Kent, Ohio. "My grandparents still live there. I was familiar with Kent and knew the area well.... it was a combination of having a chance to play and an opportunity to help change the culture a little bit. We did my senior year. It was a good experience and I’m glad I picked it.”[1] Kline redshirted the 2008 season before playing in all 12 games of his redshirt freshman campaign in 2009.[6] In 2010, he started in eight of 12 games, then started all 12 games in 2011, making seven starts at right tackle before sliding inside to right guard for the final five games.[6]
As a senior, Kline primarily played left guard as he earned second-team all Mid-American Conference honors as the Golden Flashes had their best season in 40 years, going 11-3 overall, winning the MAC East title and playing in the MAC Championship Game, which they lost in double overtime to Northern Illinois University.[7] They earned a berth in the postseason GoDaddy.com Bowl, where they were defeated 17-13 by Arkansas State University.

Just days before the Patriots' final preseason game, on August 26 the perennial All-Pro Mankins was traded to the Tampa Bay Buccaneers,[19] a move expected to provide an opportunity for increased playing time for Kline, who started the final preseason game.[20] However, after a subpar performance in that game, Kline was on the inactive roster for the regular season opener against the Miami Dolphins.[21][22] Prior to the Patriots' second game, against the Minnesota Vikings, he was again added to the active roster.[23] and saw action on eight plays in the fourth quarter.[24] He was returned to the inactive list for their next three games[25]

Kline made his first postseason start January 18, 2015 in the AFC Championship Game against the Indianapolis Colts following an injury to rookie center Bryan Stork, which resulted in guard Ryan Wendell moving to center and Kline at right guard. Kline earned praise for his performance as the Patriots dominated the Colts 45-7 to advance to Super Bowl XLIX.[32] Kline then earned a Super Bowl ring as the Patriots defeated the Seattle Seahawks 28-24 in Super Bowl XLIX on February 1, 2015.[33] Kline was one of two Patriots (the other being backup quarterback Jimmy Garoppolo) who was active but did not play any snaps.[34]
